First time reactive dog owner- advice, please!

Hello! First time poster but I have been reading as many posts as I can to learn more. I am not a first time dog owner but I am a first time reactive dog owner. We adopted her at the end of June and she is the sweetest in the house to us (my husband and me). However, she is so reactive on a leash with people and dogs. She is a pity mix so she is strong. I have a two hook leash for safety- one on her harness and one on her collar. But, she can pull so hard. I have high value treats, a mark word and will try to turn her in a circle and around to give her a distraction. It doesn’t work. I have to drag her back to my house. While she is pulling and lunging so hard that I have almost fell. Please tell me your tricks or recommendations. Or tell me to be patient and keep doing it.

I need a harsh truth.

Thank you all so much!
